Its a demo of my game 'They're Coming',which is a RPGish map that is about a teenage man and his girlfriend,she wants to join the UEAF marine corps and see the stars,he follows her and are chosen to be part of the security forces of the first succesful colony on mars. Strange appearances and disappearances have the colony on edge and finally a full out infestation of an alien species threatens the fate of humanity (which was found in an excavation) was kept secret untill the outbreak. You'll most likely find the demo bland and boring,but the real game will be 20x better with: accuall marines(squad of 4,Rico,Romero,Bigs,Johnson),multiple weapons for each marine,cut scenes,thrilling wavs for game tension,a really good storyline,expect one marine to die at a point in the game!
